- Yeah, Voodoo being the people behind the AMOS 3D extension.
-
- IIRC this rotation thing is a bug in the extension.
-
- You could write your own equations to figure out the correct
- roll/pitch angles and then simply orient the object/viewpoint
- accordingly.
-
- Alternatively, though I haven`t tried it myself (yet), you
- might be able to get the rotations correct if you reset the
- orientation of the object so that it`s not rotated at all,
- then do the rotation about the vertical axis, and then
- re-rotate the object back so that it`s pointing in the
- direction it originally was...
-
- ...if you see what I mean!
-
-
- Hmm, I can see I`m going to be coding tonight :-)

- How fast is fast? I`ve got some 16 colour starfield stuff
- using the 3D extension, that I think managed about 5 fps
- on my 030/25 (these days it rarely, if ever, drops below
- 25 fps :-)
-
- If you`re remotely interested, I`ll stick a copy of this code
- on my website next week, along with any solution I may come
- across for the 3D rotation problem.
